Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

Location & Local Information
The city of Rovaniemi, the capital of Lapland, is bisected by the mighty Kemi River, offering a unique opportunity for river swimming. Public bathing in the river is allowed at designated beaches, upheld by Everyman’s Rights, which grants public access to natural waters for recreation. However, swimmers must remain cautious due to the strong currents and the river’s regulation by hydroelectric power plants. Designated areas ensure safer conditions, but the Kemi River's powerful flow makes it distinct from more tranquil lake swimming.
The Kemi River's water temperature in Rovaniemi is typically very cold, defined by its northern latitude. Throughout the long winter, from approximately November to May, the river is largely frozen, with the flowing water beneath the ice maintaining a temperature between 0∘C and 4∘C. The surface water warms up only briefly in the summer, with the peak in July seeing temperatures rise to a range of 16∘C to 20∘C in calmer sections. Outside of this short warm period, the water is too cold for casual bathing, though the Finnish tradition of winter swimming often involves a brief dip in an ice hole, even when the air temperature is far below zero.
